Performance introduction of 38kg heavy rail
38KG heavy rail, commonly known as U71Mn (manganese steel) material, is a substitute for 60kg/m heavy rail. It is mainly used in the field of railway construction, especially in situations where high strength and high wear resistance are required.
1. Material and composition:
38KG heavy rail is mainly made of U71Mn (or manganese steel), which significantly improves the hardenability, tensile strength and wear resistance of steel by adding manganese.
2. Mechanical properties:
* Tensile strength: The tensile strength of 38KG heavy rail is usually above 700MPa, and some higher standard products can reach above 800MPa. * Yield point: Its yield point is usually around 550MPa, which enables it to maintain high strength while still having good plasticity. * Elongation: Its elongation is usually above 10%, ensuring that the material is not easy to break when subjected to stress.

3. Corrosion resistance:
The addition of manganese steel also improves the corrosion resistance of steel, especially in wet or corrosive environments, extending its service life.
4. Scope of application:
38KG heavy rail is mainly used for track laying in railway construction, especially for high-speed railway, heavy-load railway and other occasions that require high strength and high stability. In addition, it is also suitable for places that need to bear heavy loads, such as mines, ports, and large industrial plants.
5. Installation and maintenance:
Compared with traditional 60kg/m heavy rails, 38KG heavy rails are easier to install and replace, which can reduce the difficulty and cost of construction. At the same time, its good wear resistance and corrosion resistance also reduce the later maintenance costs.
6. Environmental protection:
The production and recycling process of 38KG heavy rails are relatively environmentally friendly, in line with the modern green and sustainable development concept. In general, 38KG heavy rails play an important role in railway construction with their high strength, high wear resistance, good corrosion resistance and environmental protection. However, when choosing to use 38KG heavy rails, it is also necessary to consider its compatibility with other engineering components and specific engineering requirements.
